Under the Banner of Heaven

Plot Summary:

Based on Jon Krakauer's "Under the Banner of Heaven." Krakauer, the author of "Into the Wild and Into Thin Air," published the non-fiction book in 2003. It is officially described as follows.
At the core of ["Under the Banner of Heaven"] is an appalling double murder committed by two Mormon Fundamentalist brothers, Ron and Dan Lafferty, who insist they received a revelation from God commanding them to kill their blameless victims. Beginning with a meticulously researched account of this "divinely inspired" crime, Krakauer constructs a multilayered, bone-chilling narrative of messianic delusion, savage violence, polygamy, and unyielding faith. Along the way, he uncovers a shadowy offshoot of America's fastest-growing religion, and raises provocative questions about the nature of religious belief.
